    obtenir une deuxième pluralité de signaux associés à l'écoulement de fluide (104) dans le tuyau (100) ;
    traiter la deuxième pluralité de signaux afin d'obtenir un second tracé de puissance associé aux deuxièmes vortex dans l'écoulement de liquide (104) et au débit de l'écoulement de liquide (104) dans le tuyau (100) sur la deuxième plage de débit ;
    déterminer un débit réel de l'écoulement de fluide (104) sur la base d'une valeur maximale de la puissance dans le second tracé, et
    faire en sorte que le débit réel soit produit via un dispositif de sortie.
  13. Système (400) selon la revendication 12, dans lequel le dispositif de stockage non transitoire (408, 420) inclut au moins un élément parmi une mémoire (408) ou un support lisible par ordinateur (420), le système (400) comprenant en outre :
    le dispositif de sortie ;
    le tuyau (100) ;
    un premier capteur (120a) positionné sur un premier emplacement axial du tuyau (100), et
    un second capteur (120b) positionné sur un second emplacement axial du tuyau (100),
    dans lequel le premier capteur (120a) fournit un premier signal de la première pluralité de signaux, et le second capteur (120b) fournit un second signal de la première pluralité de signaux.
  14. Système (400) selon la revendication 12, dans lequel les instructions (414a, 412b) lesquelles lorsqu'elles sont exécutées par le processeur (402), font en sorte que le système (400) fonctionne pour :
    obtenir une troisième pluralité de signaux associés à l'écoulement de fluide (104) dans un tuyau (100) ;
    traiter la troisième pluralité de signaux afin d'obtenir un troisième tracé de puissance associé aux troisièmes vortex dans l'écoulement de liquide (104) et au débit de l'écoulement de liquide (104) dans le tuyau (100) sur une troisième plage de débit ;
    déterminer qu'une valeur maximale de la puissance dans le troisième tracé correspond à un débit supérieur à la moitié de la troisième plage de débit ;
    sur la base de la détermination que la valeur maximale de la puissance dans le troisième tracé correspond au débit supérieur à la fraction de la troisième plage de débit, doubler des valeurs de la troisième plage de débit afin d'obtenir une quatrième plage de débit, et
    déterminer et produire un débit réel sur la base de la quatrième plage de débit.
  15. Système (400) selon la revendication 12, dans lequel les instructions (414a, 412b), lesquelles lorsqu'elles sont exécutées par le processeur (402), font en sorte que le système (400) fonctionne pour :
    obtenir une troisième pluralité de signaux associés à l'écoulement de fluide (104) dans le tuyau (100) ;
    traiter la troisième pluralité de signaux afin d'obtenir un troisième tracé de puissance associé aux troisièmes vortex dans l'écoulement de liquide (104) et au débit de l'écoulement de liquide (104) dans le tuyau (100) sur une troisième plage de débit ;
    déterminer qu'une valeur maximale de la puissance dans le troisième tracé correspond à un débit inférieur à un quart de la troisième plage de débit ;
    sur la base de la détermination que la valeur maximale de la puissance dans le troisième tracé correspond au débit inférieur à un quart de la troisième plage de débit, des valeurs divisées de moitié de la troisième plage de débit, afin d'obtenir une quatrième plage de débit, et
    déterminer et produire un débit réel sur la base de la quatrième plage de débit.
